Mini trenchers, which are designed to install dog fencing, low-voltage lighting, drain lines, irrigation lines and more, can cut anywhere from seven to 18 inches deep.
There are three basic types of machines on the market today: the disc-type machine, which uses a large wheel with teeth mounted on it to cut the trench; the chain-type with replaceable teeth much like its larger kin; and the blade- or rotor-type, which uses, as you might expect, a replaceable blade.
Following are some mini trenchers that are available to the rental market today.
